What is the best feed for dairy cows?
Knowing what to feed cows to give more milk is essential to choosing dairy cattle nutrition practices that naturally boost milk production. The best feed for cows to increase milk production is typically high-quality forage and corn silage with the proper proportions of starch availability and digestibility.Forage Quality for Dairy Cows
Forage quality is an essential quality to look for when selecting the best feed for dairy cows to increase milk production, and high-quality corn silage and other cereal forage crops hit the mark. Small grain forages are more than just a good double-cropping option for your farm, but an excellent source of nutrition for your dairy cattle as well as an excellent way to add a high yield of highly digestible fiber to your rotation. More floury starch hybrids often yield the best results. Not only do winter small grains give you a chance to bring extra tonnage from the same land area, but they also have very high NDF (Neutral Detergent Fiber) values and low uNDF240 (undigested NDF after 240 hours). Winter small grains may also have a lower probability of butyric acid formation compared to alfalfa silages. By replacing poor forage with highly digestible cereal silage, your dairy cattle management practices can potentially achieve up to five more pounds of milk. In addition, one pound of rumen digestible starch can yield 2.7 lbs of milk.Starch Availability for Dairy Cattle
In the case of corn silage, starch availability is a big predictor of how well it feeds. 20-30 percent of the starch value depends on the amount of processing and grinding prior to feeding or ensiling. Kernel processing scores (KPS) can be a helpful guideline. Starch digestibility may differ among hybrids from 0 to 90 days in the silo depending in part on kernel processing, but all come together at about 200 days.Fiber Digestibility in Dairy Cattle Nutrition
There’s more to NDF than we often think, and this goes for all forages. Fast and slow pools and uNDF240 are both essential to understanding fiber digestibility and the role it plays in choosing the best feed for cows to increase milk production. Low uNDF240 is critical to predicting fiber digestion in cows, with high uNDF240 almost always correlating with reduced milk production. Even though no feedstuffs remain in the cow for that length of time, analysis of uNDF240 helps predict KP and KD rates in high milk-producing cows and assists in understanding the total kinetics of NDF digestion.Choosing What to Feed a Cow to Give More Milk
Based on this information, do you now know what to feed a cow to produce more milk? You want high-quality small-grain cereal forage crops with very high NDF and very low uNDF240 rates, as well as high starch availability. For example, barley, oat, rye, wheat, or triticale silage provide an excellent balance of fiber and starch for increasing milk production. Make sure to regularly test forage samples for NDF, uNDF240, and starch content to assess their suitability for your cows and optimize your dairy cattle nutrition.Other Factors That Increase Dairy Cattle Milk Production
Knowing what to feed cows to increase milk production is not the full story when it comes to dairy cattle management, however. As critical as dairy cattle nutrition is, it’s one part of a larger equation that includes many more aspects of cattle management you can’t overlook.Cow Comfort and Management
Forage is king, but comfort is queen. Ensuring that cows have access to feed, water, and resting areas is essential to maintaining their comfort and helping to maximize milk production. Every hour of rest for a cow equals about 3.7 pounds of milk. Effective time management is a crucial part of dairy cattle management for optimizing milk production:- Cows should spend no more than four hours away from feed, water, and rest.
- At least 50 percent of their Dry Matter Intake (DMI) should be present before milking.
- Feed should be provided before milking for tie-stall herds.
- Minimize concrete or tile exposure during feeding to prevent milk value loss.
